L’Oréal Recalls Acne Treatment Over Benzene Contamination Concerns

The recall of Effaclar Duo, a La Roche-Posay product, follows reports of potential cancer risks tied to benzene exposure.

L’Oréal has voluntarily recalled all lots of its Effaclar Duo acne treatment in the U.S. due to potential contamination with benzene, a known carcinogen.
Benzene exposure is linked to serious health risks, including leukemia and other blood disorders, particularly with prolonged exposure through inhalation, ingestion, or skin absorption.
The recall was initiated in coordination with the FDA, but the agency has not yet issued an official statement or mandated further action regarding benzoyl peroxide-based products.
Independent lab Valisure previously flagged benzoyl peroxide products, including Effaclar Duo, for benzene contamination, citing instability under certain storage conditions.
L’Oréal has announced plans to release a reformulated version of Effaclar Duo in the near future, though specific timelines remain unconfirmed.
